Biomedical applicationsNanomaterials have been investigated as drug delivery agents for decades. However, such systems suffer from long preparation times; high precursor concentrations detrimental to drugs; tedious multistep procedures; and the requirement of custom-synthesised expensive/hazardous precursors.

Green nanomaterials have interesting prospects as carriers of drugs and active biomolecules. A key advantage of using green nanomaterials is that the synthesis is compatible with biological and the materials properties can be tailored.
